Well, only got around to playing 1 game tonight.
Went 13/9/9 on Sniper. A few silly deaths in there, but a few were pretty fast hits from cloaked enemies pouncing.
They had at least 10 more kills than us, but we won. In no small part thanks to our BroodMother who seemed to solo the 3 bottom Dire towers and one of the ones around the Ancient. All this while we were team-fighting/dieing in the middle lane.
Whaat was close about it was that the BroodMother got a little annoyed at our lack of a push (we were pushing, but really slowly) and said they had to leave as it was taking too long (this was about 39 minutes in). They then left.
So we had 5 minutes to take out the remaining tower and the ancient while a man down. We took it down fine, it was doing it in 5 minutes that was a little awkward as we weren't really communicating well. Did it with seconds to spare though.
My understanding is that once the 5 mionutes are up the player is classed as abandoning and the game doesn't count?
